Hydrogen: The key to a more sustainable manganese production
After the hydrogen reduction process, MnO undergoes an aluminothermic reaction (heating MnO in a furnace with aluminum to create a reaction) to produce either pure Mn or manganese–aluminum alloys. If the desired product is a ferromanganese alloy, then a form of iron is added alongside the aluminum, or via another route.
